Patient number 7, cT2bN0M0 lacrimal gland cancer, pre-surgery T1-MRI and the photon or proton beam dosimetry of adjuvant radiotherapy. Total RT dose was 70 Gy in 33 fractions. Dose constraints for organs at risk: Brain stem: Dmax < 54 Gy. Left eye and left optic nerve: Dmax ≤ 59.5Gy (85% dose). Right eye and right optic nerve: Dmax ≤ 50 Gy. Optic chiasm: Dmax < 54 Gy. Right len: Dmax ≤ 18Gy. No ocular complication was noted during our study period. a. Axial view of the tumor. b. Sagittal view of the tumor. c. Photon beam dosimetry. 1d. Proton beam dosimetry
